Requirements:

Before you order an Iron Gym, make sure you have a doorway it will fit into: under about 32″ wide, with a molding above it that’s less than six inches wide and at least a half-inch thick. The top piece of the Iron Gym needs that molding above the door to “grab,” and the wide part of the bar sits across both sides of the door frame so that on your first pull-up you don’t fall on your head.
